此问题在此处已有答案：

GCC option that can cause trouble when debugging with GDB（2个答案）
5天前关闭。
我的问题基本上和breakpoint wrong place - vue问题一样。但是它出现在c++中。
当我通过单击槽线设置行断点时，断点被创建在错误的行中。例如，我单击了第28行，但断点被创建在第34行（视觉上和调试器停止）。
虽然在某些行上设置断点可以正常工作，但大多数似乎会跳转到不正确的行。
下面是来自发动机日志的日志。

1: (41828) <-1052-break-insert -f B_Not_Quite_Latin_Square.cpp:28
1: (41837) ->1052^done,bkpt={number="12",type="breakpoint",disp="keep",enabled="y",addr="0x00007ff6e0de1880",
    func="std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char)",
    file="C:\\Data\\CompetitiveProgramming\\B_Not_Quite_Latin_Square.cpp",
    fullname="C:\\Data\\CompetitiveProgramming\\B_Not_Quite_Latin_Square.cpp",
    line="34",thread-groups=["i1"],times="0",original-location="B_Not_Quite_Latin_Square.cpp:28"

字符串
我已经点击了第28行作为断点。但是在日志的最后一行，调试器返回了line=“34”中插入的断点。
下面是我的tasks.json和launch.json配置。tasks.json：

{
  "tasks": [
    {
      "label": "build",
      "type": "cppbuild",
      "command": "C:/Program Files/mingw64/bin/g++.exe",
      "args": [
        "-x",
        "c++",
        "-g",
        "-O2",
        "-std=gnu++20",
        "-static",
        "-fdiagnostics-color=always",
        "${file}",
        "-o",
        "${fileDirname}\\${fileBasenameNoExtension}.exe"
      ],
      "options": {
        "cwd": "C:/Program Files/mingw64/bin"
      },
      "problemMatcher": ["$gcc"],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ],
  "version": "2.0.0"
}

launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "(gdb) Debug",
      "preLaunchTask": "build",
      "type": "cppdbg",
      "request": "launch",
      "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${fileDirname}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "miDebuggerPath": "C:\\Program Files\\mingw64\\bin\\gdb.exe",
      "logging": {"engineLogging":true},
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        },
        {
          "description": "Set Disassembly Flavor to Intel",
          "text": "-gdb-set disassembly-flavor intel",
          "ignoreFailures": true
        }
      ]
    }
  ]
}

试用

我试着将sourceFileMap添加到launch.json中，但是问题没有解决。

"sourceFileMap":{
  "${fileDirname}": {
    "editorPath": "${fileDirname}",
    "useForBreakpoints": true
  }
},
